How do you say "Nice to meet you / Please treat me well" in Japanese?

Quick use

Use よろしくおねがいします (yoroshiku onegaishimasu) after introducing yourself, or when you are about to start interacting with someone.

Chunk or pattern

• This is a fixed social phrase.
• Learn the whole line first instead of translating it word by word.
• The phrase is used because the relationship is starting, not because you are literally asking for a favor.

Helper words and endings

• おねがいします: often works like “please,” but here the whole phrase is better learned as one social chunk.

Practical note

English does not have one exact equivalent. In a first meeting, it often plays the role of “Nice to meet you” plus “I look forward to working/talking with you.”
